Product Description
Mazzei® venturi injectors are differential pressure injectors with internal mixing vanes. The unique, patented design and precision construction of Mazzei injectors maximizes injector efficiency, suction capacity and mixing capabilities. Our injectors also have no moving parts, which simplifies maintenance, and they have much lower operating costs than less efficient systems.
HOW A MAZZEI VENTURI INJECTOR WORKS
When pressurized water enters the injector inlet, it is constricted toward the injection chamber and changes into a high-velocity jet stream. The increase in velocity through the injection chamber results in a decrease in absolute pressure, creating a vacuum that draws a liquid or gas additive through the suction port and mixes it thoroughly into the water stream. As the jet stream is diffused toward the injector outlet, its velocity is reduced and resumes its flow in a thoroughly mixed state with slightly lower energy than when it entered the injector.
PERFORMANCE
Mazzei venturi injectors operate over a wide range of pressures and require only a minimal pressure differential between the inlet and outlet sides to initiate a vacuum at the suction port. The injectors internal mixing vanes create thousands of microbubbles, which greatly increases the surface area of gas (air, oxygen, ozone, etc.) in contact with the liquid. Several microbubbles have a greater surface area than one large bubble of the same volume. Higher surface area facilitates greater solubility.
